Integrated nickel masses per solid angle in all directions displayed in 4π maps for models W15-1, W15-2, L15-1, and L15-2 at postbounce times well after all nucleosynthesis processes have seized in our simulations. Red crosses indicate the NS kick direction while white plus signs mark the direction opposite to the kick. The corresponding hemispheres are separated by a white equator line. Note the differences between the high-kick W15 models and the moderate-kick L15 models. The former show a clear enhancement of the nickel production in the hemisphere opposite to the kick, whereas the latter eject nickel significantly more isotropically.
